fix(paths): gracefully handle nulls for local cleaning filters

[thmsobrmlr]

Problem

Duplicating an insight leads to nulls in the query. For the local path cleaning filters this resulted in a crash for a customer.

Changes

Gracefully handles null values for the local path cleaning filter.

Follow-ups

• Look into wether duplicating an insight creates these nulls, and if so - fix that -> could not reproduce
• Python doesn't distinguish between null and undefined, meaning we have no protection from "faulty" queries like this in our backend side validation. Likely we should add nulls to the whole schema.ts types where we have an optional value.

How did you test this code?

Used the query from the customer locally to verify the issue and fix.
